Atkins diet works. But you have to read the book. So many people talk about it and don't know wtf they're talkinga bout. Atkins diet isn't about no carbs---it's about zero to 20 carbs on the induction (14 days when you start) and then up to 40, and eventually a maintenance where you figure out how many carbs you can eat w/o gaining weight.
I'm a lard ass, but it's because I don't exercise enough. I've sucessfully used the Atkins diet to lose 50 lbs, but I put it back on when I went off of it b/c I wasn't exercising. The biggest benefit of mine on the Atkins was I didn't realize how much sugare was in my diet.
But all in all-----if you're willing to read the book, and willing to follow the directions with discipline, it's a good way to jumpt start weight loss. If you follow the atkins diet with no exercise, and then just quit it and go back to eating like you were pre-atkins. You'll put the weight right back on.
I think Atkins is good for jump starting weight loss, and for aid in getting your diet under control, but I struggle with the notion of it being a way of life. As for people saying it's unhealthy----you have to quantify that. Atkins and high protein diets promote a state of keytosis in your system, which is hard on the kidneys----ppl with diabetes can sometimes struggle with elevated keytones b/c their kidneys' don't function right. The keytosis is triggered b/c you're body is burning fat for energy instead of converting your carb/sugar intake. Also---if you do a calorie anaylsis of a FDA recommended meal vs the atkins diet, you'll notice that you're also taking in less total calories a day.
That being said---there's been more then one study, that while it doesn't offer a legitmate reason----it has acknowledged that people on the atkins diet (especially those that are obese) experience not only a reduction in choloesterol (the bad cholesterol) but also a reduction in blood pressure, despite the fact that they are on a high-fat diet.
So---in closing---yes--it works. No, I can't do it long term---i get sick of meats----but when combined with exercise, and discipline, it's an excellent way to lose weight.
